possible bug in montage IM 6.5.2-3 Q16

[fmw42]

IM 6.5.2-3 Q16 Mac OSX Tiger

Some of my scripts are not working now. I have tracked the problem down to what appears to be a problem in montage.

The following simple test does not seem to finish.

montage -label "test" -geometry +0+0 logo: logo_montage.gif

Is this a bug or has something changed in using montage?

[magick]

Works for us (i.e. it completes immediately) under Linux. Add -debug all,trace to your command line and see if you can identify where the process is handing.

montage -debug all,trace -label "test" -geometry +0+0 logo: logo_montage.gif

This is where it hangs

[magick]

There have been no recent patches to the methods listed in the debugging output. Try a complete uninstall and reinstall. Be sure to check the permissions on the ImageMgick configuration files (i.e. type.xml).

[fmw42]

I will try re-installing.

But the changelog shows a recent change affecting montage. Might that be connected in some way?


2009-03-28 6.5.1-0 Cristy <quetzlzacatenango@image...>
Support -unsharp option for the montage program.

[magick]

Don't think so. It was a patch in the montage option parsing and unfortunately we cannot reproduce the problem.

[fmw42]

I am reinstalling now and will let you know. Did you test under Mac OSX Tiger?

[fmw42]

I have now reinstalled, but still have the same problem.

I did a make distclean. Then deleted the ImageMagick-6.5.2-3 directory. Then downloaded a fresh copy from ftp://ftp.imagemagick.org/pub/ImageMagick. Then reinstalled with:

./configure --enable-delegate-build --enable-shared --disable-static \
--with-modules --with-quantum-depth=16 --with-gslib --without-wmf \
--enable-libtool-verbose --disable-dependency-tracking \
--with-gs-font-dir=/usr/local/share/ghostscript/fonts/ --with-lqr


After the installation was complete, I tried the same command:

montage -label "test" -geometry +0+0 logo: logo_montage.gif

But it hung again.


I checked the permission on type.xml

cd /usr/local/lib/ImageMagick-6.5.2/config/
ls -al type.xml
-rw-r--r-- 1 root wheel 671 May 8 17:45 type.xml

Does it need changing?

Thanks.

[magick]

We can reproduce the problem you posted and have a patch in ImageMagick 6.5.2-4 Beta available sometime tomorrow. Thanks.

[fmw42]

Thanks. I appreciate your looking into this. Glad it could be reproduced.

[fmw42]

We can reproduce the problem you posted and have a patch in ImageMagick 6.5.2-4 Beta available sometime tomorrow. Thanks.

I just downloaded and installed the IM 6.5.2-4 release and tested again:

montage -debug all,trace -label "test" -geometry +0+0 logo: logo_montage.gif

but it still hangs.

Might it not have been included in 6.5.2-4? Should I try 6.5.2-5 beta?

Thanks

Fred

We may have a possible bug in the OpenMP gomp library. Edit magick/annotate.c around line 1576. Comment out this line:

• #pragma omp parallel for schedule(dynamic,4) shared(status)

and rerun your montage command line. Does it still hang? If so try rebuilding ImageMagick without OpenMP support:

• ./configure --disable-openmp
  make
  make install

Does montage work now?

[fmw42]

Bottom line --- neither solution made a difference.

We may have a possible bug in the OpenMP gomp library. Edit magick/annotate.c around line 1576. Comment out this line:

• #pragma omp parallel for schedule(dynamic,4) shared(status)

and rerun your montage command line. Does it still hang?

This did not work. But I am not sure I did that correctly. Pardon my ignorance. I edited the file located in the ImageMagick-6.5.2-4/magick/ directory. I could not find any such file at /usr/local/bin.

If so try rebuilding ImageMagick without OpenMP support:

• ./configure --disable-openmp
  make
  make install

Does montage work now?

This did not work either. Here is the configuration command that I used and then did make, sudo make install.
./configure --enable-delegate-build --enable-shared --disable-static \
--with-modules --with-quantum-depth=16 --with-gslib --without-wmf \
--enable-libtool-verbose --disable-dependency-tracking --disable-openmp \
--with-gs-font-dir=/usr/local/share/ghostscript/fonts/ --with-lqr


Afterwards, the same command still hung.

montage -label "test" -geometry +0+0 logo: logo_montage.gif

[magick]

Run montage and let it hang. Determine its process number with the 'top' program. For our example, assume a PID of 12345. Type

• gdb montage 12345

Now type 'where' to the gdb command line prompt. Post the stack trace here so we can analyze the problem.

We put the montage program in a loop on our Mac OS X laptop and it ran pver 2000 times without fail before we bailed. We're using ImageMagick 6.5.2-5 Beta from ftp://magick.imagemagick.org/pub/ImageMagick/beta.

My error. After --disable-openmp and rebuilding IM 6.5.2-4 Q16, it appears that the command does finish. I just did not wait long enough in my test.

time montage -label "test" -geometry +0+0 logo: logo_montage.gif

real 0m5.722s
user 0m1.107s
sys 0m0.327s

And my script is now working again.

Sorry for the false alarm. I will double check without disabling openmp and let you know if perhaps I was too hasty with my original test on the upgrade to IM 6.5.2-4.
